:The Schedule referred to in these Letters Patent: and making part of the same.

Be it known that I, HUGH H. Canam, of the city and State of New York,`ha ve invented,v made, and ap plied to use acertain new and useful Improvement in Traps for Stationary Wash-Basins, &c. and Ido hereby declare/the following toy he a full, clear, and exact` `description of the construction and operation of the same, reference being had tcthe annexed making part of this specification, wherein- Figure 1 is a vertical section of my improved trap,

drawing,

as applied to the bottom of anordinary stationary basin;

Figure 2 is a plan of the trap; and i Figure 3 is a `vertical section of the trap, in the form adapted tothat class of basins in which the overi'low-ppeiis made in the basin itself.

Similar marks of reference denote the same parts. In stationary basins, it has heretofore been usual to have a brass ferrule in the bottom of the basin, for receiving the plug, and in which ferrule arercross-bars,

to prevent large substances passing into the pipe for A the waste water. i

These cross-bars catch and detain hairs, lint, Snc.,

that accumulate and stop the free escape of water,

while matches,l hair-pins, andsimilar articlesmay pass into the pipe and choke the same. This former char` acter of ferrule allowed smallvalnable articles, accidentally left in the basin, to escape and be lost in the wastepi'pe. f V

The object of my invention is to remove these diy culties by allowing the free escape of such articles as will be readily washed awaysu`ch as lint, Snc., and at the same time detaining permanent obstructions, such as matches, &c., and also catching small valuable articles, vsuch as rings, pins, 8vo., thatmight be in the'A basin, and accidental]yiallowe'd` to pass into the wastej My inventionoonsists of ametaltrap, screwed upon the ferrule of the basin, and forming a nut, to clamp said ferrule to its place, and the ferrule and trap acting together, to exclude smell from the waste-pipe, and retain any substances that might obstruct the wastepipe if allowed to pass into the same.

In the drawing, crepresents aV portion of the stationary wash-basin, with an opening in thebottom, as usual, through which passes `the ferrule b, having a ange, 2, as usual, and adapted to receive the plug c.

On the outsideV ofthe ferrule b is ascrew-thread, upon which the trap d is screwed, so that the basin is clamped and the parts rendered water-tight by the Washer e.

At the lower part of the trap is a screw, f, that can be taken out, for removing any substances that may remain in the trap, and the stop-plate, at g, 'passing down below the surface of the water that remains in the trap,'prevents smell passing into the basin from the escape'or waste-pipe h, that' is coupled or otherwise connected to the trap d. s

`sides communicating with said overflow-pipe c'.

It willnow be seen that the water is retained suliciently to trap smell, a free escape is provided for small i oating particles that will not obstruct the pipe, solid;

substances are detained, and the trap can be cleaned' out with great facility.

If desired, cross-bars or a movable strainer might `be introduced in the ferrule b below the plug. A set- .nut' might 'intervene between the trap and basin upqn 4 the ferrule ,7), but it is not necessary.

j By connecting the waste-pipe to the trap by means of couplings, the parts can be disconnected with facility for repairs if required. .This trap might be applied to a pantry-sink or similar article containing the ferrule and plug.

What- I claim, and desire to secure by Letters Patent, is Y 1. The trap d, screwed upon the ferrule l, and acting asa nut to clamp the ferrule b and washer to the ling of "the Waste-pipe and the ferrule and plug ot theA basin or sink.

'In witness whereof, I have hereunto-set my signature, this 11th day of December, 1868.
